To all whom 'it may concern.' l

Be it known that I, GEORGE SLoCo'uEE wDAVIS, a subject of Vthe King of Great lBritain and Ireland, `residing at Kenilworthf Bellevue street, Kogaraln'in` the State of New South-Vales, .Commonwealth of Aus-` tralia, have invented certain new anduse# ful Improvements in Railroad Stock-Trucks,

of which the following is a'specification.

This vinvention relates to the cooling and.

" roads and confined in trucks, and is distinct from the supplyingof drinking water to live stock under such conditions. f

The ob] ect Vof the invention is to provide in a railroad truck or wagon adapted for carryingV such live stock, means whereby the stock'may be cooledor refreshed asrequiredV by a light shower .of water while the trucker wagon is traveling, thus avoiding the waste of time hitherto entailed in side tracking the stock train for this purpose, and obviating the employment of trucks having removable or sliding roofs. y

My invention consists in the combination with a railroad truck (adapted for the 'carriage of stock) of means such as are hereinafter described and illustrated in the accompanying drawings for achieving the before stated object.

In the drawings Figure 1 is a plan view of the roof of a railroad stock-truck litted up in accordance with this invention, and

Fig. 2 is a longitudinal partly sectional elevation of the top portion of the truck. Fig. 3 is a transverse sectional elevation on line 3 3 of Fig. 1 and Fig. 4 is a similar view on line 4 4 of Fig. 1; while l Fig. 5 represents at about full size a section of the drip-valve employed.

The stock truck illustrated is of the type having a transversely curved roof but it will be understood that the invention is equally applicable to trucks with fiat roofs.

10 represents a water-containing tank housed in a box 11 on the roof covering of the truck, said tank being provided with a filling aperture 12 projectin through the top of the housing and closa le by a removable cover 13 which is preferably of sufliciently loose fit to permit the passage of air. The tank is iitted internally with baffles 111.14 to minimize surging of the water, and is suppDrted upon bearers 15.15.

'Io the bottom of the tank at each end are connected outlet pipes 16.16 to which are connected plug cocks 17.17 each provided with an operating-lever 18, said cocks and levers being so arranged that the arc of movement of the latter is in a plane at right angles to the sides of the truck.

To maintain each cock in the closed position its operating lever 18 is counterbalanced byl a weight 19 and as a further safeguard a coil spring 2O exerts a pull on the lever in the same direction as said weight.

Said cocks are each connected toa separate reticulation pipe system extending over the roof of the stock compartment and con forming to the sectional configuration of the roof;randeach reticulation system come prises a longitudinal pipe 21, a transverse pipe y22, a return longitudinal pipe 23, a transverse pipe 24, and a further return pipe 25.

At close intervals in the pipes 21 and 23 of each reticulation system are T pieces 26, 26, the branches of which are directed downwardly and pass 4through apertures in the roof of the truck; and at each end of pipes 23 and the end of pipes 25 are crossiittings 27 of which one branch is directed downwardly through the roof of the truck and the other upwardly; and into the latter are screwed vertical vent pipes 28 open at the top and through which vair may escape thus preventing the formation of air-locks in the pipes. `The connection between the longitudinal and transverse pipes is made by cross `fittings 29, into the unconnected branches of which are screwed plugs.

Into each downwardly directed branch of the fittings in the reticulation pipes is screwed a drip valve 30 of particular construction and comprising (see Fig. 5) a body 31 screw threaded externally at one end and cored or bored to provide an axial passage 32 and achamber 33, the junction of said passage and chamber constitu-ting a valve seat 34. The chamber 33 is screw threaded and a plug 35 screws therein, said plug having an extension 36 terminally constituting a valve 37, and a hexagon head 38 whereby the plug may be turned in the body and the required adjustment of the valve effected, the plug being locked in the adjusted position by a jam-nut 39.

Vater from the tank is admitted to the reticulation pipes as and When required by opening the cocks 17, and for the manipulaY tion of the latter, flexible Wire cords Lil are attached to the levers 18, passed over the edge of the roo-f of the truck and through an eye 42. The cords are terminally fitted With a ring i3 which is looped over" a hook 44: to maintain the cocks in the open position. Water passing the valve 37 escapes from the chamber 33 by lateral oriiices 40 and drips with such frequency as is desired from the outside of the drip-valve on to the the roof thereof, a reticulated pipe systemy above the roof thereof, air-vent stancbpi'pes connected to said system, a connection between said tank and pipe system, a cock in said connection means for operating saidV cock from the side of the stock compartment,

C opies offshis patent may be obtained for nected to the bottom of the tank at each end,

counterbalanced levers attached to the 'plugs of said cocks, springs to normally close the n cocks, flexible cords attached to said levers,

said cords leading over the edge of the roof of the car and being terminally provided With rings which engage hooks to retain the cocks in the open position, a systemjof reticulation pipes connected to each ofsaid cocks and extendingl over the roof of the car, air ventsl in said pipe systems, each of the latter comprising longitudinall andl transverse pipes jiuictioningwith` each other,` and at short. intervals in said reticulation pipes downwardly directed branches passing through the roo-f of the truck, and each pro- Xf'idedvvith a drip valve.
